Our global tunnels have been dropping multiple times a day since the 5.1.0 upgrade. Complete instability. No changes to our config, no ISP issues on our end.

Support case opened, but they're pointing fingers at our SD-WAN. That's nonsense—it was rock solid on 5.0.9. Anyone else seeing this? Specifically with IKEv2 tunnels to on-prem firewalls.
